Essential oil compositions were obtained by Clevenger and recognized by GC-Mass and GC. According to results, the majority of seedlings were injured in autumn planting date (November) and effect of planting seasons on fresh and dry biological yields and essential oil of foliage were significant. In spring (March) and summer (June), fresh and dry biological yields were 5.4, 1.1 kg/m2 and 3.7, 0.8 kg/m2, respectively. Essential oil quantity was also 10.2 and 5.3 cc/m2, respectively. The most important components in essence were carvon with 58.5 and 52.2% in spring and summer seasons, respectively. Thus, cultivation of dill in spring and summer seasons in order to produce seed, foliage and essential oil was successful.}, keywords = {Carvon,Dill essential oil,Spring Planting,Summer Planting dates}, title_fa = {مقایسه اثر فصل کشت بر خصوصیات زراعی و عملکرد کمی و کیفی شوید}, abstract_fa = {برای مقایسه اثر فصل کشت بر عملکردهای بیولوژیکی، بذر و اسانس بذر و اندام رویشی شوید، آزمایشی در قالب طرح کاملاً تصادفی با سه تکرار در سال زراعی 1386-1385 در مرکز تحقیقات کشاورزی و منابع طبیعی استان اصفهان انجام شد و طی آن سه تیمار کشت پاییزه، بهاره و تابستانه مقایسه شدند. در این آزمایش از توده شوید اصفهان استفاده شد و کشت پاییزه این گیاه موفق نبود. تفاوت وزن تر، وزن خشک، عملکرد اسانس اندام رویشی و ارتفاع گیاه در دو فصل دیگر کشت معنی دار بود (در سطح احتمال یک درصد). میزان ماده تر در کشت تابستانه و بهاره به ترتیب 4/5 و 7/3 و میزان ماده خشک 1/1 و 8/0 کیلوگرم در مترمربع و عملکرد اسانس اندام رویشی 2/10 و 3/5 میلی لیتر در مترمربع بود. در کشت بهاره و تابستانه، ماده Carvon به ترتیب با مقادیر 5/58 و 2/52 بالاترین درصدهای ترکیب اسانس را داشت.}, keywords_fa = {اسانس شوید,عملکرد,کشت بهاره,کشت پاییزه,کشت تابستانه}, url = {https://jci.ut.ac.ir/article_23257.html}, eprint = {https://jci.ut.ac.ir/article_23257_162eda7489f4df80f18fb0720418969f.pdf} }
